One dimensional flow with heat transfer of a pseudoplastic fluid between two infinite horizontal parallel plates is investigated. The thermophysical properties of the fluid are assumed to be constant and numerical solution using the finite element method, along with the corresponding exact solution for the fluid velocity and the fluid temperature is obtained. The effect of variation of the governing parameters is studied using figures and tables. It is found that the numerical solution agrees well with the corresponding exact solution and that the fluid velocity, together with the fluid temperature, increases with increasing values of the governing parameters.

The pseudoplastic circular Couette flow （CCF） in annuli is investigated. The viscosity is dependent on the shear rate that directly affects the conservation equations solved by the spectral method in the present study. The pseudoplastic model adopted here is shown to be the suitable representative of nonlinear fluids. Unlike the previous studies, where only the square of the shear ered to ease the numerical manipulations, quadratic power is also taken into account. rate term in the viscosity expression is consid- in the present study, the term containing the The curved streamlines of the CCF can cause the centrifugal instability leading to toroidal vortices, known as the Taylor vortices. It is further found that the critical Taylor number becomes lower as the pseudoplastic effect increases. The comparison with the existing measurements on the pseudoplastic CCF results in good agreement.
